BIOS.SysSecurity.AcPwrRcvry (Read or Write)
Description
Specifies how the system reacts after AC power has been restored to the system. It is especially useful
when systems are turned off with a power strip. When set to Off, the system stays off after AC power is
restored. When set to On, the system turns on after AC power is restored. When set to Last, the system
turns on if the system was on at the moment when AC power was lost. The system will remain off if the
system was turned off when AC power was lost. In case of an ungraceful shutdown, the system always
turns on.

up delay is defined by the User Defined Delay field.
